DETAILED DESCRIPTION

In order to make the objectives, technical solutions and advantages ofthe present invention clearer, the technical solutions in theimplementations of the illustrative solutions of the embodiments of thepresent invention are clearly and completely described hereinafter withreference to the accompanying drawings of the specific embodiments ofthe present invention.

With reference to FIG. 1 to FIG. 3, a skating machine includes a rack100, supporting shafts 200 and a synchronizing assembly. The twosupporting shafts 200 are hinged to the rack 100 side by side, pedals300 are hinged to top portions of the supporting shafts 200, and thepedals 300 are eccentrically arranged relative to the supporting shafts200. At the moment, the pedals may make a circular movement, and adiameter of the circular movement may be adjusted according to differentgroups of people. The synchronizing assembly is arranged between the twosupporting shafts 200 and enables the two supporting shafts 200 to actsynchronously, which may make the two supporting shafts rotate in a samedirection, and may also make the two supporting shafts rotate in anopposite direction.

Specifically, the rack in the embodiment includes an underframe 101 andan armrest frame 102. The underframe 101 is formed by welding aplurality of rectangular steel tubes, assembly cavities of twotransmission assemblies are formed at two ends of the underframe 101,and transmission parts of the supporting shafts and the synchronizingassembly are arranged in corresponding assembly cavities. The armrestframe 102 is arranged above the underframe 101, a guide sleeve 103 isarranged on the underframe 101, a supporting leg of the armrest frame102 is matched with and slidably arranged in the guide sleeve 103, and alocking member is arranged between the guide sleeve 103 and thesupporting leg. The locking member may be a locking bolt, and a screwhole is formed in the guide sleeve 103, such that the armrest frame isfixed by abutting against the supporting leg with the locking bolt.

The synchronizing assembly includes synchronizing wheels arranged atbottom portions of the supporting shafts 200 and a synchronizing chainarranged between the synchronizing wheels. At the moment, synchronousrotation in a same direction may be implemented, a bevel gear set mayalso be arranged in the middle, and two bevel gears in the bevel, gearset are in transmission connection with corresponding supporting shaftsrespectively through the synchronous chain, thus changing a direction.In the drawing of the embodiment the following structure is adopted,which means that the synchronizing assembly includes a synchronizingshaft 401 arranged on the rack, and two ends of the synchronizing shaftare in transmission connection with corresponding supporting shaftsthrough the bevel gears 402. In the structure, the supporting shaft 200and the synchronizing shaft 401 are both supported on the underframe 101through a bearing seat 403, and in order to improve a stability of thesupporting shaft 200, the bottom portion of the supporting shaft 200 maybe provided with a thrust hearing for jacking, thus improving a bearingcapacity and a stability.

Since some special groups of people need physical rehabilitation andcannot drive the pedals through the body by themselves, a drivingportion may be arranged, and the driving portion is in transmissionconnection with one of the supporting shafts through a clutch. In theembodiment, the driving portion includes a diking motor and a gearbox,such that rotation with different intensities can be implemented, thusdriving the body to simulate skating and implementing coordinatedrehabilitation training of the whole body. The driving portion isconnected with the supporting shaft through the clutch, and a speed ofthe gearbox is adjusted to control a rotating speed of the supportingshaft.

In the embodiment, there are two types of fixing structures for thepedals and the supporting shafts. In one of the fixing structures, asupporting disc is used. As shown in FIG. 5, the supporting disc isfixedly arranged at the top portion of the supporting shaft, and thepedal is hinged to the supporting disc. The supporting disc may also beused as a counterweight disc, such that a high-intensity simulatedmovement can be implemented, thus leading to a certain inertia force.Similar to skating, when there is the inertia force, it is relativelydifficult to start, but an endurance and a training intensity of along-time movement can be improved. In addition, it takes a long time tobrake, such that a brake assembly, such as a wire brake, a V brake, adisc brake and other brake structures, may be provided to brake thesupporting shaft and the supporting disc, thus avoiding an impact forcecaused by directly driving the pedals through legs.

In the present application, in the other connection mode between thesupporting shafts and the pedals, a supporting rod is provided. At themoment, if the counterweight disc is provided, the supporting rod andthe counterweight disc may be arranged separately. As shown in FIG. 6,the counterweight disc, the resistance adjusting assembly and the brakeassembly may be in the same form as the supporting disc.

In addition, in the above structure, adjusting holes are formed in thesupporting disc or the supporting rod in the above structure, and thepedal is matched with and assembled in a part of the adjusting holes205, such that a trajectory radius of the pedal may be adjusted.

In order to optimize a simulation degree of skating simulation and carryout different forms of exercise, in a circumferential direction of thesupporting shafts, the two pedals are arranged in the same directionrelative to the respective corresponding supporting shafts, or and thetwo pedals are arranged at 180 degrees relative to the respectivecorresponding supporting shafts, such that two pedals may be arranged atthe top portion of one of the supporting shafts, and are arranged in thesame direction as that of the pedals of the other supporting shaft andare arranged at 180 degrees with the pedals of the other supportingshaft.

The resistance adjusting assembly 203 is arranged on the rack 100, theresistance adjusting assembly 203 is arranged corresponding to one ofthe supporting shafts 200 and adjusts a resistance of the pedal 300, andthe structure may implement both brake pad resistance adjustment ormagnetic control resistance adjustment. In the embodiment, a brake padresistance adjusting structure is provided, which includes a supportingseat, an adjusting rod and a resistance block, the resistance block isarranged corresponding to any one of the supporting shaft, thecounterweight and the supporting disc, and the adjusting rod adjusts theresistance block and an acting force thereof.

The counterweight disc 202 and the brake assembly need to be provided atthe same time, such that a braking safety can be ensured at the momentand an impact of forced braking on a human body is avoided. Therefore,the brake assembly may be arranged corresponding to the counterweightdisc or the supporting shaft, thus implementing braking.
